When the time comes that he wants to do something to richen up the tune a bit, the following thread has a good overview of the popular options with the pros and cons.

Thanks Kevin for the tuner thread. It really has a lot of good info. I'm thinking maybe my SIL and I buy a PowerVision with one extra tune and split the cost. We both win! Thanks guys!

The Powervision marries to the engine so I'm not sure you could get an "extra" tune without extra dollars.

+1....good choice no tune

Looked at the FuelMoto site and they show a PV1 and a PV2. Since I have a 2012 SG and he has. 2014 Slim, it looks like they require different versions, so may have to call them to find out. It was a thought anyway!

The only difference between PV-1 & PV-2 is the data cable which can be purchased separately for $24.99. You can use a single PV unit to tune both the 12 SG and 14 Slim, this would require a Power Vision unit, data cable, and a tune license. We can set the unit up ready to flash both bikes no problem.

That's great! You got to me before I could get to you, now that's customer service! That would solve our problem for sure. Thank you so much Jamie for the info. I'll be calling you soon!

Not just for slip ons, slip on alone and the O2 sensors will compensate for the exhaust...change the breather you need to remap the ecm

He is going to most likely get some decel pop and its most likely going to sound a bit harsh...I know cost is a factor, however, spending the extra bit, even for an FP3, will make all the difference. Having done it, I would do the same thing.
This is good advice. For a Stage 1 setup this is the best cost effective upgrade package to get a performance gain, better throttle, improve mpg and eliminate decel pop. Hiflow A/f, slip ons (this will decat a Softail) and a flash tuner, such as an Fp3 or Superchips Vigilante EZ Tuner. About $750 if you do the labor yourself. You will be surprised how good a Twin Cam can run. With regard to your OP, no you don't have to tune with only a muffler upgrade.

I have Rush Slip Ons with 2 Inch Baffles, did not touch the air filter or fuel management. Runs like a dream! I go buy the old saying, "If it ain't broke, don't fix it."
